摘要：

The room temperature oxidation (up to 2500 L) of a Zr-Fe getter having Zr2Fe as majority component (810% of the total volume) is studied with X-ray photoemission (h-nu = 1253.6 eV) and Auger spectroscopy. Core photoemission (Zr 3d, Fe 2p and O 1s) and ZrM45N23V Auger spectra have been measured for increasing oxygen exposure. The oxidation proceeds via an interface suboxide up to an oxide having about the same chemical shift as ZrO2 (4.3 eV). At saturation the reacted overlayer is about 6 monolayers thick. A small fraction of Fe is found in the reacted overlayer (concentration around 15% of that of the substrate).
